Game Mechanics: Kanras: NPCs have the potential to gate starting at 20% of their health

[getsome]

Observed a NPC being engaged on his spawn point gating more than five times and regenerating his health each time.

Is this the intended mechanic implemented from this patch? My recollection of this mechanic was that when you cleared to a npc and fought the npc on their bind point, they would not attempt to cast gate.
